No-Script Suite Lite — AdblockLite

No-Script Suite Lite provides an extra security for your Firefox browser. It allows JavaScript (inline & external) to be executed only by trusted websites of your choice. Some websites are added to the white-list by default, but you can add or remove items at any time.

Important features:
a) Allows you to block all Scripts (inline and external) from untrusted websites (plus you can block Images, Objects, Styles and Media as well).
b) Simple and very lite: this addon does not use noticeable memory or CPU form your machine.
c) You can easily switch the extension On or Off from the toolbar popup UI.
d) Add or remove websites to the white-list table easily from toolbar-popup.
e) Beside scripts, you can also block style-sheets, images, objects and media from untrusted sources. To activate, open toolbar-popup and click on the desired option at the bottom of the panel.
f) Choose desired blocking engine, WebRequest Observer or Content Security Policy from the options page.
g) Add desired whitelist or blacklist rules with regular expressions.
